Production Experience:Huamei group has been lending exporters of rubber plastic insulation materials for these 10 years in China.The company is located in the heartland of Beijing,Tianjin and Hebei and the Bohai Sea economic circle,Huamei is a large conglomerate incorporating research,development,production and sales. China Well-know Trademark:Huamei brand was awarded the honor in 2010. Good Anti Bending:Hunamei products have good flexibility and tenacity which makes it easy to handle bent and irregular pipe in construction,saving both labor and material. Good Fire Blocking: Huamei products with self-extinguishing characteristic has a lot of flame retardant and smoke reduction raw materials,and low smoke density generated during the combustion.And when touched the fire it should not be melted and dropping the fiery-balls. Good Damp-proof Property: Huamei products has perfect closed pore foaming structure.Each of the apertures are independent of the others.The independent aperture-closing can form much hindrances to moisture,so even if the surface of the material was damaged,it also can prevent the water vapor into the inner material,so that maintaining the long-term steady of the heat-insulation effect . Low Conductivity Factor:Conductivity factor is a very important index to measure the heat-insulation effect of the thermal insulation material.The lower the conductivity factor is,the better the heat-insulation performance will be. Good Vibration Resistance: Huamei products with high elasticity,and thus can minimize freezing water and hot water pipe in the process of using in vibration and resonance. FM Certificate:Huamei Melx Class0 has successfully passed FM Global company’strict-examination and testing for product thermal conductivity,moisture permeability and fire performance,obtained the FM certificate and was authorized to printed mark <FM>.
